Duwamish River Community Coalition

Seattle, Washington

Duwamish River Community Coalition volunteers advocating for their community.

When a river runs through a community, county or state, everything that goes into its waters and everything that flows through it impacts everyone who lives on it, or near it.

The Duwamish River is the name of the lower 12 miles of Washington state’s Green River, and it is the only river in the city of Seattle. Carrying the name of the Duwamish People, whose name means “the way in,” the river flows through South Seattle, past Georgetown and South Park, through an industrial area, under the West Seattle Bridge and empties into Elliott Bay. Unless visitors and residents put some effort into it, they may rarely see the river.

Over the last century, the Duwamish river has shaped Seattle and in turn, Seattle’s industries have shaped the Duwamish River. After settlers arrived in 1850 and began to build, the river was dredged and straightened in 1913, providing space for industry to move in. By 1920, most of the Duwamish Waterway had been dredged to a depth of 50 feet. “The shallow, meandering, nine-mile-long river was transformed into a five-mile engineered waterway capable of handling ocean-going vessels.”

And with that change came the inevitable cost to the communities that call the river and Seattle home. 100-years of industrial pollution, runoff and sewage overflow brought the river to be designated a Superfund Site by the U.S. Environmental Protection Agency (EPA) in 2001 who  called it one of the nation’s most toxic hazardous waste sites. The clean up plan includes 5.5 miles of the Duwamish River and 412 acres of land. More than 40 chemicals are in the river bed and need to be removed, including cPAHs which are the most harmful to people.

In that year, 2001, the Duwamish River Community Coalition formed. Their mission for this program, as described on their website, is to be “involved in all aspects of the cleanup of the Duwamish River. We are working to ensure the cleanup meets community standards by restoring environmental health and protecting the fishers and families who use the river as well as reflecting the priorities, values and will of the people who live and work in the region.”

The last part of that statement is the cornerstone of the organization. They envision a representative body of African-Americans, Native Americans, Cambodian, Latinx, Vietnamese, and Somali immigrants and refugees, all governing for themselves how the resources that impact their lives so thoroughly are managed. 

Alberto Rodriguez, outreach coordinator for the Duwamish River Community Coalition talks about his journey through the superfund process and cleaning up Seattle’s Duwamish River, which has suffered from 100 years of industrial pollution.

The same principle applies to work with The Clean Air Program. In addition to toxic chemicals polluting their waters, the industries and the traffic that goes with them has caused “Beacon Hill, Georgetown, and South Park (zip code 98108) [to have] the highest ranking for air pollution compared to other neighborhoods in Seattle,” according to a health impacts analysis. It was discovered that the highest concentration in the city of diesel and benzene particles was in those communities. Incidents of asthma are statistically high among children and adults in these communities.

Together with data collection through surveys, community and youth-led research, and mapping of assets and threats to the communities’ health, the Clean Air Stakeholders Group has created a draft list of actions for each prioritized strategy as their work continues in 2021.

In a recent bill signing for the HEAL Act, Governor Inslee lifted up the work of organizations such as the Duwamish River Community Coalition in his comments. For those who love and protect the river, the reasons for doing so are clear, but perhaps Executive Director, Paulina López, said it best in an interview in early 2021: 

“I look at the eyes of our youth that we work with every week,” said Lopez. “I look at the eyes of my kids. I really am not going to give up until I know they can breathe better air and have access to all the opportunities other youths and other neighborhoods have given to them.”
